My invention re es to iniproim-inenls in a weft replenishing loci of the class shown 7 described in U. billet! Patent, N0.

tor feelers, one for each shuttle; which .i lm-s have a longitudinal movement and also an movement in the arc of a circle, and in invention articularly relates to improvements in the fil ing detector mechanism of the or no shown and described in said patent, in which electro-magnets having movable cores or feelers are used.

It has been found in practice in the class of looms referred to, that it is desirable, alter the feelcr in line Wiiii the raceway of the lay has been moved backward bv its engagement with the lillin filling ioally be moved 'forwaru or on moves lnickward, preparatory to feeling l the filling on the next forward movement of the lay, and also that any o e oi the feelers, or all oitbe feelers, should moved forward from t ieir roar position, and po; tively maintained in their forward operative position, preperW-Wv to indicating practical exhausiion oi lug detector 3 on oi the (ill me b.. o A trainin v its io rward normal position, For a predetermined. time preparatory to its indicating substential exhaustion of filling.

lily inxention consists in certain novel foaturcs of construction of my improvements, as will be hereinafter fully described.

I have only shown in the drawings a do taclied portion of a loom, and a filling do icclzor or fccler mechanism of the type shown in said Patent, No. 808,966, with my imp EUVP" merits combined therewith, and ednptcd in e used on a. two box, and eto :r cox. loci Some of the parts shown in the drawings and connected with and 'l'orming a part of the iilling detecting n'urhnnism, are of the same constrluztion and operation as shown in U. S. letters Patent, No. 805,109.

Fig. 5 shows the operating lever for the feelers, shown in Fig. 2, detached. Fig. 6 corresponds to F ig. 4, but shows a. filling detecting mechanism for four shuttle boxes. Fig. 7 is e section, on line 7, 7, Fig. 6, looking in the direction of arrow (1, same figure. Fig. 8 is a section, on line 8, 8, l 6, looking in the direction of arrow f, samefigure, and, Fig. 9 shows the stationary arm and the operating lever for the feelers shown in Fig.7 detached.

in the accompanying drawings, Figs; 1 to 5 inclusive show the filling detecting mechantwoshifting s uttle boxes, with mv im rovements combined therewith, and I wil first describe the same.

1 is the upper par t of a loom side or frame at the front of'tlie loom; is the breast rm-elm, 3 is a bracket or stand bolted to the 1 in frame, and supporting at its outer end siand i, at the upper end of which are suitable bearings i for a shaft 4", on which is mounted the hub (5 ol' the filling detector or feeler carrying frame 6, which has a pivotal motion in a vertical plane, through the rod '7 connected with the vertically movin shuttle box rod, not shown. The irame 6 has supported thereon at its inner end two electroniagnets, each having iilling detectors or feelers 8, one for each box or cell of the two shifting shuttle boxes, not shown, and for each shuttle 9 having therein a bobbin 9.

The feelers 8 correspond to the feelers shown and described in said Patent, No.

5,966, and each consists of a balanced i l l i l l l l i bins therein, and by broken lines a different ism of the tyfiie referred to for a loom with of movement ofthe feelers magnetic body or pin free to have a iongi dinsi movement Within the center or" e coil c Wire 10, through which an electric current is adapted to pass, in wires 11 and 12, contact plates 67, s ring blades llend l2, and wires l1 end 12 leading to opghvsite poles of any suitable source of eleetiie energy, and formin a solenoid, or electro megnet, all as fufiy de scribed in said Patent No. 808,966.

The feelers 8 are preferably spirally grooved longitudinally on their external surfaces, to form channels or recesses in vwhich eny particles of dust or dirt may collect to leave the peripheral surface oig' said-feelers smooth and even; 1

In connection with the filling detectors or feelers 8 is used a, detector arm 13, having a 1 hub 13 centrally pivoted on a stud 14. The

upper end of stride-rm. 13 extends in the path 8, and is adapted to be moved back or" the same. A spiral spring 15;;is supported. on thestud 14, and is secured at one end on said stud, and engswes with its other-end the upper part of the testing arm '13, and sets to moveit back or" the feelerS hich isinline with the receway of the 183;, when said i'eeler is moved ion werdly on preeeicel exheustion of 39 i The detectingfermli has a downwardly i extending srn'i.;which is'pivoteily coiinected with '2. red 1.6, which"preferably extends tren I seiy through he loom to t 0 seatsreplenishing end thereof; end EsconnectedQwith-the trensferrer mechanism, not shown, of the eft replenishing mechanism. A longitudinally moving rod 1? is guided in a stand 18, extending out from the bracket 3. ,end its inner end is adapted to engage the detecting arm 13 heiow its pivotal support, as shown in F The opposite end. of the longitudinally. moving rod is attached to one arm of enengle lever 19, pivotally mounted on a stud 19 the other arm of rod. ,20, which hes a regular intermittent movement communicated thereto from some driven art of the loom, and causes the move merit of the angle-lever 19, and the longitw dinal movement of the rod 17 to cause it to engage the detecting arm 13 below support, and to positivei y ineve end of said arm sway hem the feeiers 3 Te uler intervals, and also to be moved swel r a l I this instance by means the s ngle lever 19 is attached to e verticeliy moving evens s, sirer i l engagement W,

F ig. l, to hold ssid e n 23, end positively maintain the lei in its forward position, in engagement n th the feelers 8, to positively position endjhold the feelers 8 in their forward operative position. At the proper time, the movement of the rod 17 in an outward direction, will release the arm 23 from the set screw 24. and lee-Ye the lever 27 free to be moved back by the outward movement of a feelcr 3, as above described.

I will now describe my improvements applied to a four box loom, and shown in Figs. 6, 7, 8, end 9 of the drawings. In said figures, the some figures of reference are used as in the preceding figures, for similar ports. The filling detecting frame 6 carries four electrommgncts, ench homing it fceler 8, one for each of the four shuttles 9. The vertically moving rod is in this instance pivotellv connected with 1d of St lQVl 3'2,

mounted on a. stud the stand t. A huh UL connector 3e is pivotally ettucheiil t on:- and to a pin 32 on the lever 32, and at s other end to :1- pin 35 on an arm 35 on the 6 of the feeler supp mechanism for en gsi feelers 25 into their lorw ii. p tively maintaining t; position, consists in Ll tionm'v engaging; RL'Ul lower end an offset are shaped portion 0 sin ""l'r:une 6. My moving the ion, and posi their normal ncc of :1 Sid ll has on lug 13h secured to the stzmd 4 by screws 37, see Figs. 6 and S, and at us upper end the curved engaging surface 35 of :t-DCl adopted to (i\-" lQ--: the feelers 8, when they are above the p no i' f e men-why of the lay. Below the suga part 36" the arm 36 is offset, as shown l 9, to admit of the cngiifng part 1" v the rocking ope-retina; lever 38, corresponding to the operating lever extending in the path 27 nl'iovi: described. The engaging part 38 of the o 'icrnting lever 88 extends in the path of Hill is ndapted to engage the feelci' H which in line with the race-way of the luy. The operating lever 38 has two huh portions 238 which are loosely mounted on studs 31*.) on the stand 4, and n downwardly nod outwardly extending; engaging :li'lil 3. of inclined or as shown by brokenv end pivotully 1 extension 4 on i com shape on its inner engaging surface, as shown in Fig. 8, and extending in the path of and adopted to be engaged by the set screw 24 on the collar 25, sdjustably secured by a. set screw on the longitudinally moving rod 17. Extending below the engaging part 38 of the operating'lever 38, end in the some vertical pl zine therewith, and with the stationary engaging surface 36 of the stationary arm 36, is a slotted plate 40, formed in this instance by a bar 40 secured to the stationary arm 36 by a screw 41. The slotted plate 40 is edaptedto receive the headed outcr'end of a feeler 8, as the feelers 8 arcmoved down 'ith their supporting frame, to hold said feelers, and prevent them from dropping out of the coils of wire 10. The two leaf springs 28' and '29, which are preferably; used, are attached at their inner ends on the stand 4, and engage with their free ends the operating lever 38; one spring, as 28, actin on the lever 38 above its pivot point, and

the other spring, as 29*, below itspivot point, as shown in Fig. 6. The s ring 29 corresponds to the spring 29, e ove described, and acts to move forward the lever 38, and yieldingly hold it against a stop 38, end in engagement with the outer end of the feeler 8, in line with the race-way of the lay. The spring 28 corresponds to the spring 28, above described, and acts in the same Way.

The operation of my mechanism for a. four shuttle box loom, to move the feelers 8 for ward, and to positively maintain the some in their normal position, will be readily understood by those skilled in the art. As the feelers 8 are raised and lowered with the supporting; frame (5, to extend in c plztne above or below the rn-ce-wnv of the lay, the leeler or feelers above the plane of the raceive-y of the lay, will engage with the stution-' sry engaging surface 36 of the stationery ltilil 3(3, and be moved.forwnrd and peertivcly nmintiiined in their normal position, and the fccler or feelers below the plane of the race-way of the lay, will be engaged by the slotted plate ll, and be maintained in their proper position, while the fceler in line with the race-way of the lay will be engaged by the engaging end 38 on the operating lever 38, hnd moved forward and )ositiyely maintained in its forward normal position by the set screw 24 extending back of the inclined end of the arm 38" of the lever 38 to hold said lever in its forward position, the same above described in connection with the lever '37. The movement of the set screw 24 into the recessed part of the engaging arm 38 will "release the lever construction of my improvements maybe 131' a movable core -g agmg and positioning each movable core or V51- ied if desireti, and they may mix-"pied to be 'used in oomieotion with shifting shuttle boxes having two or moi'e'oeiis for ohm-Silos.
